On Tuesday (October 10), the dollar began the trading session higher by 0.21% at R$5.1751. The Brazilian stock market's main index, the Ibovespa, is also set to open with attention to global market stability after the recent tensions stemming from the conflict between the United States and Iran. President Donald Trump’s comments indicating that the war is 'practically over' and potential easing of oil sanctions have calmed some investor nerves, prompting a cautious optimism in markets worldwide.

However, uncertainties still loom regarding the normalization of oil transport through the Strait of Hormuz, a critical route for oil globally. The region's geopolitical tensions continue to drive market volatility as traders remain warily focused on oil supply fluctuations. The collective market response indicates that while there is some easing of immediate pressures, the economic implications of further instability in the region could still lead to unpredictable shifts in both currency and stock prices.

As of the latest figures, the dollar has accumulated a weekly loss of 1.52% and a year-to-date decline of 5.91%, while the Ibovespa index shows a weekly gain of 0.86% and a yearly increase of 12.28%. These market indicators reflect both the recent geopolitical developments impacting oil prices and the overall sentiment among investors looking for stability amid ongoing uncertainty.
